Open caisson heading machine guiding system based on static inclinometer and method thereof

The invention relates to an open caisson heading machine guiding system based on static inclinometers and a method thereof. The open caisson heading machine guiding system based on the static inclinometers comprises two inclinometers arranged on an inner wall of each open caisson segment, wherein the two inclinometers arranged on each open caisson segment are located on two straight lines in the vertical direction correspondingly; and the inclinometers in the open caisson are arranged in two longitudinal rows in the vertical direction. The system is advantaged in that technical problems that the attitude measurement process of the underwater heading machine is tedious, precision is poor and cost is high are solved. 本发明为一种基于静态倾角仪的沉井掘进机导向系统及其方法，该基于静态倾角仪的沉井掘进机导向系统包括设置于每节沉井管片的内壁上的两个倾角仪，各节所述沉井管片上设置的两所述倾角仪在竖直方向分别位于两条直线上，以使沉井内的各倾角仪在竖直方向上形成两纵排排列。本发明解决了水下掘进机的姿态测量过程繁琐、精度差、成本高的技术问题。
